IMPROVEMENT IN GRAlN-SEPARATORS.

Specification forming part of Letters Patent No. 43,036, dated June 7, 1 64.

To all whom it may concern.-

Be it known that I, AARON HIGLER, of

Chicago, in the county of Cook and State of Illinois, have invented new and useful 1mprovements in Grain-Separators; and I do hereby declare that the following is a full and complete description of the construction of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a top view. Fig. 2 is an end view. Fig. 3 is a side view. Fig. 4 is a longitudinal vertical section, and Fig. 5 is a detached part.

Like letters of reference denote like parts in the several views.

A represents a hopper of the usual form, through which the grain passes into the mill.

Nos. 1', 2, and 3 (shown in Fig. 4) represent screens arranged one above another, through which the grain passes and by which it is separated aceordingto the quality and deposited in different drawers, hereinafter to be described. A shaking motion is given to these screens by means of the rock-shaft b, connecting-rod b, and wheel b, which gears into the wheel d on the end of the fan-wheel shaft. The shaker N is suspended at the tail end by the rods 02 n, Fig. 2. The upper shoe, F, is suspended in like manner by rods f, and this shoe is provided with screens Nos. 4, 5, and 6, arranged one above theother, as seen in Figs. 1 and 4. To the upper screen, No. 4, I attach the fingers a, which extend into the hopper to agitate the grain and cause it to pass over the screen.

The desired motion is given to the shoe F by means of the rock-shaft c, connecting-rod mill.

At t in Fig. 4 in the shoe F, and below the screen No. 5, is shown a sieve or screen which discharges ,upon the screen No. 6. Below the screens that communicate with the spout D are inclined planes extending down on each side to the spout, as indicated by the dotted lines imFig. 3.

e is a wind-trunk between the upper shoe, F, and lower shoe or shaker, N, conveying the wind from the fan-wheel through the falling grain.

To the outside end of the upper sieve, No. 3, in the shaker N is arranged a gage-slide, h, that can be moved or adjusted so as to take on more or less ot the grain as it fallsfrom the upper shoe.

An adjustable slide-deflector is shown at m, which conveys the heavier tailings into the drawer K.

The sieve No. 3 communicates with the spout J, and the sieve No. 2 communicates with the spout I. These troughs incline downward toward the spout, so that the grain which enters them runs down freely and out of the mill. The inclined table 0' communicates with the drawer L, and the sieve No. 1 communicatcs with the drawer H. The shoe N, being suspended from the sides of the mill by the rods n, which are longer than the rods f,which suspend the upper shoe, F, and the wheel I) being larger than the pinion d, the vibrations of: the lower shoe are longer and slower than the upper one. The first quality of larger grain passes over the sieve No. 3 into the spout or trough J, and the second quality of smaller grain falls upon the finer sieve No. 2 and passes into the spout I.

In the end of the, sieve No. 3 there is a slide, G, (shown in Fig. 5,) that can be removed when the grain in place of passing over the end of the sieve into the spout J will fall through the opening caused hy-the removal of the slide into the spout I, that the sieve No. 2 empties into, thus uniting the first and second qualities ot'grain in the spout I, the sieve No. 3 being a little coarser than the sieve No.2.

-lhe elastic stops 1' are for the purpose of easing the reaction or striking of the shoe against the sides of the mill.

The hopper A is provided with a gate, 0,

which is adjusted by a screw to admit more or less from the hopper into the mill. Fingers a are attached to the upper screens, by the action ofwhich the opening from the hopper into the mill is prevented from clogging, as hereinbefore indicated.

In the operation of this machine the wheat .the grain operated upon) are screened out.

The wheat, cockle,ohess, grass-seed, &c., fall upon the screen 4, when the grass-seed passes through and falls upon the apron E in the bottom of the shoe F and is carried into the trough D and out of the spout D. The grain and other seeds too large to pass through the screen 4 are carried over and precipitated over the gage h. At the same time all the tailin gs are blown out of the grain by the blast of wind passing through the wind-trunks, the heavy portion of the tailings being carried into the drawer K by means of the deflector m,'which can be so. set as to catch more or less, as desired. At the same time the adjustable gage h at the top end of the sieve 3 can be moved forward or backward, so as to catch more or less of the grain to be cleaned. The grain passes from the hopper through screens 4 and 5 and falls upon t, where the wheat falls through, and larger seeds--as oatspass ov'er and through the screen 6, and fall into and are discharged through the spout a, while the sticks and short straws are received into and discharged through the spout a. The small pats or other small grain pass down through to the lower one and then to the spout a, while the wheat falls upon the sieve 4 and is separated from the grass-seed, as before stated.

The same principle is employed in cleaning all kinds of grain and seed as in cleaning wheat, only the difierent kinds of grain or seed requiring diflerent kinds of screens and sieves, the meshes of which must be according to the size of the grain or seed to be cleaned, the shoe 13 being the same and arranged so as to receive the different kinds of sieves and screens, or rather the difl'erent sieves and screens being made to fit the shoe, the action of all the partsbeing the same. In passing the trunk all the light' stuti' is blown away,

. spout J whilcthe smaller and imperfectgrain, with the cockle, passes through the screen N o.

3.-into the sieve No. 2, where it is again screened,'an.d the wheat, which is of the sec- .2, and out of the spout I. The wheat that is screened through sieve No. 2 into screen No. 1 is of a third quality, and passes over the screen into drawer H, while the cockle is screened through and falls upon the inclined table z, and passes into the drawer L. The cockle and chop-stuff is screened through all of the sieves and passes into drawer L, while grass-seed and other of the same size, will pass out of the spout D. It the screens and sieves are arranged in the shoe F for cleaning flaxseed, the yellow seedand pull-down seed, 850., would be discharged through the spout D. the slide deflector, m, pass into thedrawer K, and the light tailings are blown away.

When it is desired to have the first and second quality of wheat together, the slide G in the screen 3 is removed, and the. wheat will pass out through the slide opening into the spout I.

The object of having a reduced motion to the lower screen with a longer stroke is that by a quick motion all the light seeds tend to rise to the top of the heavier grain or seed on the screen; but' by reducing the motion, so that the grain will not lie'still, all the small seeds and foulwheat will drop through the screen. In the upper shoe the object is to shake-a quick and'sho'rt stroke, so that all the larger and lighter seeds-such as oats, straw, &c.-will rise to the top to allow the grain to be screened through.

What I claimas my improvement, and desire to secure by Letters Patent, is-' 1. The adjustable deflector-gage m, in combination with the gage h and. receiving-box K, substantially as and for the purpose set forth.

2. The arrangement and combination of the pinion d, gear-wheel b, the connecting-rods b and d, rock-shafts b4 and 0,.for the purpose set forth.

3. The trough D, in cbmbiuation with the screen 4 andapron E, arranged and operating as and for the purpose specified.

4. The slide Gr, screens 2 and 3, in combination with the spouts I and J, as for the purpose set forth.

5. The vibrating rake a, when attached to either the upper or lower shoes, and used in combination with the separator, substantially as set forth.
